This series is similar to that for the AST2500 but I've split the patches out
as the AST2600 driver is new for 5.4 and I'm hoping we have a chance of
slipping them in. Maybe we can get both series in, but I thought decoupling
them might make it more manageable if not.

Regardless, the blurb:

This series is two small changes enable kernel support for controlling the RMII
RCLK gate on AST2600-based systems. RMII is commonly used for NCSI, which
itself is commonly used for BMC-based designs to reduce cabling requirements
for the platform. NCSI support for the AST2600 is not yet implemented in
u-boot and so unlike the AST2500 the kernel can't rely on RCLK already being

Please review!
